2 Claims.

This invention relates. to structures fol t ddy assembly anddisconnection of units as to coaxial relation against relative angularshifting.

This invention has utility as between a rotatable shaft, a sleeve, axle,hub and the like and a pulley, gear and a road wheel. More particularadvantage arises in the removal of road wheels for motor vehicles, whichmay be effected quickly, independently of tools. The chauffeur orvehicle driver may quickly take-off a vehicle wheel, esp cially ininstances of trouble, and repl c as readily by a spare. An ins ance ofembodiment has to do with providing the support of axle region with anannular group of lugs, having overhang in one direction as from aradially extending disk face. The central region of a wheel disk, aboutits axial opening has a series of openings or ports adapted to registerwith the lugs, take a slight angular shift, with the opening clearancesas to the lugs now filled by locking ring blocks. The ring is adaptedfor spring pin assembly at the locking position.

Referring to the drawings:

Fig. 1 is an edge view of the attachment assembly, say looking from therear toward a right hand side road wheel, mostly broken away or indotted showing, with a fragment of the wheel disk central portion insection in the region of the axle;

Fig. 2 is an edge view of the lug-carrying axle region;

Fig. 3 is a partial view looking from the right of Fig. 2;

Fig. 4 is a side elevation of the central region of the wheel disk;

Fig. 5 is a section on the line VV, Fig. 4;

Fig. 6 is a side elevation of the locking ring to seat in the disk;

Fig. 7 is an enlarged view of the ring from the line VII-*VII, Fig. 6;and

Fig. 8 is a detail view, in section as to the mounting, of one of thepair of assembly maintenance pins for the locking ring, the showingbeing on an enlarged scale.

For a motor vehicle of the automobile type, having a brake drum l at ahub plate region 2, there is to be located a wheel disk 3 for apneumatic tire 4. A'stub axle 5 is shown protruding from the plate 2coaxially of the disk 3 and the tire 4.

Under the invention herein, there is located concentric of the axle 5 toprotrude from the plate 2 a plurality of hook lugs 6. In a common, sayfollower side direction, each lug 6 has an arc-shaped overhang l as to aseat 8.

The disk 3 about its ax p nin 9 as a annular s ri s i are=sha ed s otsrts li The disk 3 is, accord ngly ada ted t be us on the axle 5 for thhoo ugs 6 to regist r With the ports 10. The disk 3 has its inner faceI! abut the outer face 12 of the plate 2, at which position there may bea counterclockwise relative shifting of the disk 3 as to the plate 2 tobring it straight radial lug side l3 in the port It] against straightradial port end It. There is thus established thruout the annular seriesof lugs and ports an abutting angular stop assembly of the seats 8 withthe overhangs l snugly against disk 3 outer face l5.

A clearance I6 is thus left in each port iii aft the lug 6. Qver theaxle 5 is now thrust alocking ring I! having an annular series of blockoffsets I8 to seat in each clearance It in such snug coaction as to holdthe radial sides I3, M, abutting. Rising from a plurality of the blockregions of the ring I! is a slide guide R9 for a spring pin 20,yieldably inwardly thrust by a helical compression spring 2! to ride ina registering port 22 of the axle 5. A bushing 23 on the pin 20 beforethe head is mounted on the pin, has thread assembly with the guide [9 tolocate the spring in position. A set screw 24 locks the bushing 23 withthe guide IS. A key 26 radially slidable thru the pin 20 on the outerface of the bushing 23, rides under an overhang or hook 21, to lock thepin 2c in the axle seat or port 22 against being thrown out bycentrifugal force in high speed rotation.

Considerable advantage ensues in carrying thru the subject-matter of theinvention as herein disclosed. In the event there be road mishap, remotefrom access to tools, there is of course requirement to provide axlesupport to clear the wheel from the road. However, from here on, thedriver with only hands, may pull the pins 2!) thereby clearing thelocking ring I? for takeofi, or at least getting the blocks 18 away fromthe clearances l6. From the held axle, it is now only necessary to givethe wheel but a slight rock to move the lugs 6 back into the clearancesIt. The axial direction lock between the axle and the wheel is nowreleased by the overhang portion 1 of the lugs B being retracted fromriding over the face [5 of the disk 3. The lugs 8 are now in axialregister with the ports Iii and it is only necessary for the driver tocomplete the uncoupling by now pulling the wheel on in a direction awayfrom the plate 2.

The remount, that is, placing of the spare, is speedily effected in thereverse sequence.

The seat means 9 is slid over the coaxial seat means 5 with angularpositioning to locate the ports It], so that completion of the thrust ofthe disk side II is to abut the plate side I2. The bayonet joint seriesin a radial plane is now at an assembly stage. Angular shifting nowcauses the overhangs 1 of the hook lugs 6 to ride on the disk face 15 tolock axially the disk face II in abutting relation with the plate facel2. This shifting limit is with the lug seat face 13 against the portend face l4. Considering it one move- .ment to bring the ports I0 intoregister with the lugs 6 and have the disk and plate members :abut, thesecond movement is the few degrees in angular shift for setting thebayonet joint. There is now the third movement, to apply the lockingring I! for its blocks l8 to enter the clearances 16, and as this isbeing done, the spring pins 20 enter the axle stub seats 22.Precautionary setting may now be taken thru having the key 26 under thehook 27. The spare is now fully placed for safe driving, preferably thruthe lugs away from the clearances, altho the blocks I8 effectivelyrespond in reverse direction transmission.

What is claimed and it is desired to secure by Letters Patent is:

1. An automobile demountable wheel assembly on a plate-providing axle,said plate having an axle stub protruding therefrom and an annularseries of hook lugs thereabout, said wheel including a disk regionproviding a complementary series of ports to register with the lugs and,at relative angular shifting, to anchor axially the wheel with the axleand in said shifting to expose clearance at the ports adjacent the lugs,a ring adapted to be thrust over the axle stub against the plate, saidring having blocks coacting at plate contacting position of the ring toseat in the port clearances directly to laterally abut lugs shifted fromsuch clearance portions of the ports and thereby lock the wheel againstangular shifting relatively to the axle plate, and spring pin meanscoacting between the ring and axle stub to hold the ring with its blocksin Wheel mounting assembly.

2. A demount coupling for an automobile wheel, said coupling comprisinga pair of opposing plate members, one member providing an annular seriesof ports and the other member a complementary concentric annular seriesof lugs coacting in assembly to provide bayonet joints, a locking ringhaving an annular series of wedges insertable in the ports against thelugs to lock the plate members assembled by the bayonet joints, andradially extending spring pins carried by the ring, one of said membershaving seats for the respective pins thereby to hold the ring with thewedges in the ports in maintaining the joints in locked positions.
